CP477 Trial of Dissolved Oxygen
Monitors in Wastewater Applications

This collaborative project brought together 10 UK Water companies and 9 technology suppliers to independently evaluate, fully understand and define the performance of a 12 wastewater dissolved oxygen monitors under real conditions.

The 12 month trial was hosted by Severn Trent Water and assessed the performance of the instruments on both surface aeration and fine bubble diffused aeration in activated sludge wastewater treatment. The results of this work were used by the participating water companies to inform maintenance and procurement decisions. Supplier used the results to demonstrate performance under fully independent assessment.
